* [lit] Improve readability of failing scripts.Daniel Dunbar2016-06-026-14/+69
| | | | | | | | | | | | | | | | | | | | | | | - This only applies to scripts executed by the _internal_ shell script interpreter. - This patch reworks the log to look more like a shell transcript, and be less verbose (but in the interest of calling attention to the important parts). Here is an example of the new format, for commands with/without failures and with/without output: ``` $ true $ echo hi hi $ false note: command had no output on stdout or stderr error: command failed with exit status 1 ``` llvm-svn: 271610

* Add "REQUIRES-ANY" feature testEric Fiselier2016-06-024-3/+19
| | | | | | | | | | | | | | | | Summary: This patch adds a "REQUIRES-ANY" feature test that is disjunctive. This marks a test as `UNSUPPORTED` if none of the specified features are available. Libc++ has the need to write feature test such as `// REQUIRES-ANY: c++98, c++03` when testing of behavior that is specific to older dialects but has since changed.

* Add auto-exporting of symbols from tools so that plugins work on WindowsJohn Brawn2016-05-261-0/+488
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem with plugins on Windows is that when building a plugin DLL it needs to explicitly link against something (an exe or DLL) if it uses symbols from that thing, and that thing must explicitly export those symbols. Also there's a limit of 65535 symbols that can be exported. This means that currently plugins only work on Windows when using BUILD_SHARED_LIBS, and that doesn't work with MSVC. This patch adds an LLVM_EXPORT_SYMBOLS_FOR_PLUGINS option, which when enabled automatically exports from all LLVM tools the symbols that a plugin could want to use so that a plugin can link against a tool directly. Plugins can specify what tool they link against by using PLUGIN_TOOL argument to llvm_add_library. The option can also be enabled on Linux, though there all it should do is restrict the set of symbols that are exported as by default all symbols are exported. This option is currently OFF by default, as while I've verified that it works with MSVC, linux gcc, and cygwin gcc, I haven't tried mingw gcc and I have no idea what will happen on OSX. Also unfortunately we can't turn on LLVM_ENABLE_PLUGINS when the option is ON as bugpoint-passes needs to be loaded by both bugpoint.exe and opt.exe which is incompatible with this approach. Also currently clang plugins don't work with this approach, which will be fixed in future patches. Differential Revision: http://reviews.llvm.org/D18826 llvm-svn: 270839

* SDAG: Make SelectCodeCommon return voidJustin Bogner2016-05-101-2/+3
| | | | | | | | | | | This means SelectCode unconditionally returns nullptr now. I'll follow up with a change to make that return void as well, but it seems best to keep that one very mechanical. This is part of the work to have Select return void instead of an SDNode *, which is in turn part of llvm.org/pr26808. llvm-svn: 269136
* [TableGen] AsmMatcher: support for default values for optional operandsSam Kolton2016-05-061-31/+117
| | | | | | | | | | | | | | Summary: This change allows to specify "DefaultMethod" for optional operand (IsOptional = 1) in AsmOperandClass that return default value for operand. This is used in convertToMCInst to set default values in MCInst. Previously if you wanted to set default value for operand you had to create custom converter method. With this change it is possible to use standard converters even when optional operands presented.

* Remove LLVM_ENABLE_TIMESTAMPSChris Bieneman2016-05-051-2/+2
| | | | | | | | | | | | | | | | | | | Summary: As per the discussion on LLVM-dev this patch proposes removing LLVM_ENABLE_TIMESTAMPS. The only complicated bit of this patch is the Windows support. On windows we used to log an error if /INCREMENTAL was passed to the linker when timestamps were disabled. With this change since timestamps in code are always disabled we will always compile on windows with /Brepro unless /INCREMENTAL is specified, and we will log a warning when /INCREMENTAL is specified to notify the user that the build will be non-deterministic.

* Remove bit-rotten CppBackend.James Y Knight2016-05-051-2/+0
| | | | | | | | | | | | | | | | | This backend was supposed to generate C++ code which will re-construct the LLVM IR passed as input. This seems to me to have very marginal usefulness in the first place. However, the code has never been updated to use IRBuilder, which makes its current value negative -- people who look at the output may be steered to use the *wrong* C++ APIs to construct IR. Furthermore, it's generated code that doesn't compile since at least 2013. Differential Revision: http://reviews.llvm.org/D19942 llvm-svn: 268631

Currently, %t\%t is, for example, expanded to C:\foo\C:\foo, which is not a valid path because ":" is not a valid path character on Windows. With this patch, %t will be expanded to C\foo.

* Add IntrWrite[Arg]Mem intrinsic propertyNicolai Haehnle2016-04-194-9/+40
| | | | | | | | | | | | | | | | | | | | | | Summary: This property is used to mark an intrinsic that only writes to memory, but neither reads from memory nor has other side effects. An example where this is useful is the llvm.amdgcn.buffer.store.format.* intrinsic, which corresponds to a store instruction that goes through a special buffer descriptor rather than through a plain pointer. With this property, the intrinsic should still be handled as having side effects at the LLVM IR level, but machine scheduling can make smarter decisions.

* Update and fix LLVM_ENABLE_MODULES:Richard Smith2016-04-161-4/+0
| | | | | | | | | | | | | | | | 1) We need to add this flag prior to adding any other, in case the user has specified a -fmodule-cache-path= flag in their custom CXXFLAGS. Such a flag causes -Werror builds to fail, and thus all config checks fail, until we add the corresponding -fmodules flag. The modules selfhost bot does this, for instance. 2) Delete module maps that were putting .cpp files into modules. 3) Enable -fmodules-local-submodule-visibility, to get proper module visibility rules applied across submodules of the same module. Disable -fmodules for C builds, since that flag is not available there. llvm-svn: 266502

| | | | | | | | | | | | | | | | We could make this an option if people don't like it. But since part of the reason for using a script to generate checks is to prevent lazy checking that lets bugs crawl through, let's have the script check the first line too. For asm tests, it ensures that nothing unexpected has happened before the first line of asm. This matches the existing behavior of update_llc_test_checks.py.
